”Rheumatism” is a confusing term for both patients and doctors. The two sides are often far apart. It is a very old word, first appearing in the Hippocrates’ Complete Works more than 2,000 years ago. Doctors at that time believed that disease was caused by bad body fluids in the body, and that where the fluids flowed through caused abnormalities in the function of that part or organ. “The disease caused by “bad body fluids” that flow down to the limbs and internal organs due to dampness and cold is called “rheumatism. In the Emperor’s Classic of Internal Medicine, it is written that wind, cold and dampness are combined to form paralysis. It can be seen that the current popular term “rheumatism” refers to pain, swelling and other discomfort in joints, muscles and bones caused by cold and moisture. In modern medicine, the meaning of the term “rheumatism” has been greatly changed. If the following conditions occur, it is time to consider rheumatology diseases and seek help from a professional rheumatologist: joint pain and swelling; muscle pain and weakness; skin rash; dry mouth and eyes; severe hair loss; mouth ulcers; vulvar ulcers; fever that does not respond to anti-inflammatory treatment; discoloration of fingers when cold.
